高空系留气球的防雷系统设计

Lightning Protection Design of Tethered Balloon System

高空系留气球的雷电防护是一项极其复杂的工程,目前国内外都还没有针对高空系留气球的雷电防护标准。本文从设备雷电防护的原理出发,在充分分析雷电可能对系留气球囊体表面及球上电子电气设备造成损坏的基础上,提出了一种基于法拉第笼等电位方式的新型防雷设计方案。本文重点对防雷杆、避雷索和导电装置等关键部件进行详细设计,从而确保系留气球遇到雷击时能够安全运行,最后利用缩比模型的雷电防护试验对设计方案的防雷效果进行了验证。

The lightning protection of high altitude tethered balloon is a very complex project.At present,there is no lightning protection standard for high altitude tethered balloon at home and abroad.Based on the principle of lightning protection,a new lighting protection design scheme based on Faraday Cage Equipotent mode was proposed on the basis of fully analyzing the possible damage of lightning to tethered balloons and the harm to workers.To ensure the safe operation of tethered balloon in case of lightning stroke,the key components such as lightning rod,lightning cable and conductive device were detailed designed.Finally,the lightning protection test of the scale model was used to verify the lightning protection effect of the design scheme.
